AUTOMATIC DIFFERENTIAL LOCKING SYSTEM

摘要

An automatic differential locking system for a working vehicle having steerable front and rear wheels, includes a selector for selecting a steering mode of the vehicle, an actuator for operating a differential locking mechanism, and a gate for sending a control signal to the actuator in response to a signal received from the selector. The gate is adapted to send a differential locking signal to the actuator upon receipt of a parallel steering mode signal from the selector. In response to the differential locking signal?the actuator actuates the differential locking mechanism. Since differential revolutions of the wheels are limited in the parallel steering mode, the vehicle is capable of accurate course revisions and alterations without slipping. ?
